具体实施方式
以下由特定的具体实施例说明本申请的实施方式，熟悉此技术的人士可由本说明书所揭露的内容轻易地了解本申请的其他优点及功效，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
根据本申请实施例，提供了一种导流增强防水卷材，如图1所示，包括防水板11、纵向导水止水带12和吊带13；其中，所述纵向导水止水带12设置于所述防水板11的表面上；所述吊带13穿过所述纵向导水止水带12和所述防水板11之间的接触面，其两端位于所述纵向导水止水带12的外侧。
本申请中的导流增强防水卷材，将吊带13通过纵向导水止水带12与防水板11的之间的连接实现固定，吊带13与防水板11的接触面较大， 不会导致防水卷材的整体性能下降。另外，由于防水板11上设置了纵向导水止水带12，避免了现有技术中防水板11采用平面状时，防水卷材在施工中会有局部顶破漏水的隐患，特别是在受隧道二衬混凝土承压后，漏点出水后由于为防水卷材为平板状，水会蔓延，确定漏点时需要大面积破除混凝土来进行确认，施工费工费时的问题，防水卷材上增加纵向导水止水带12，不影响防水卷材本身的性能指标，防水卷材挂在隧道壁后，能增强环向的整体强度。
在一些可选实施例中，如图2所示，所述纵向导水止水带12的数量为一个或者多个，当所述纵向导水止水带12的数量为一个时，其位于所述防水板11的横向中心；当所述纵向导水止水带12的数量为多个时，多个所述纵向导水止水带12沿着所述防水板11的横向间隔或者连续设置，在图2中，纵向导水止水带12的数量为三个，呈间隔分布。当纵向导水止水带12为连续设置时，相邻两个纵向导水止水带12之间互相接触即可。通过在防水板11上设置纵向导水止水带12，将防水卷材上层出水点分隔开，阻挡出水点横向蔓延，可将防水层上出现的水流导流至纵向盲沟中排出。
在一些可选实施例中，如图3所示，纵向导水止水带12包括主体部121和凸起部122，所述主体部121呈片状，所述凸起部122呈弧形、方形或者Ω形，如半圆形或者圆形等。所述凸起部122为实心或者空心的结构，当凸起部122为实心结构时，可提高纵向导水止水带12与防水板11的接触面积，从而使得纵向导水止水带12与防水板11之间固定的更加牢固，图3中，凸起部122为空心结构，可使得纵向导水止水带12的生产工艺简单。所述凸起部122的数量为多个，且多个所述凸起部122呈间隔设置，相邻两个凸起部122之间形成的导流槽将防水卷材上层出水点分隔开，阻挡出水点横向蔓延，可将防水层上出现的水流导流至纵向盲沟中排出。
在一些可选实施例中，所述纵向导水止水带12与所述防水板11的表面之间采用焊接、热熔或者粘结的方式连接，其中纵向导水止水带12 与所述防水板11的材质可相同或者不同，如选择同样的塑料材质等。
在一些可选实施例中，所述纵向导水止水带12沿着其长度方向上设有多个吊带13，其中，多个所述吊带13呈间隔分布，相邻两个所述吊带13之间的间距为1米，如纵向导水止水带12的长度方向上设置三个吊带13，相邻两个吊带13之间的间距也可以根据需要设置其他距离。
在一些可选实施例中，如图4所示，吊带13呈U形，其底部为连接部131，连接部131设置于纵向导水止水带12的下方，并与导水止水带12以及防水板11固定连接，使得吊带13与导水止水带12以及防水板11的接触面积变大。在使用时，从吊带13的两端与其他部件进行固定连接，将防水卷材吊起。
在一些可选实施例中，相邻两个所述纵向导水止水带12之间的间距为1.2米。所述纵向导水止水带12为弹性体，如橡胶或者硅胶等材质；纵向导水止水带12的强度高，下穿吊带13，借助其高强度性能整体吊起防水卷材，可以代替吊带和热熔垫片焊接吊板方式，吊板平整，避免注浆时褶皱现象。同时更便于现场施工，降低成本。
在进行尺寸选择时，防水板11的厚度1.5毫米，纵向导水止水带12的主体部121的厚度为1.5毫米，靠近防水板11的端部的纵向导水止水带12距离防水板11的端部的距离可选择300毫米，进行多个数量的纵向导水止水带12即可，相对于现有技术中的防水卷材，可利用相邻两个凸起部122之间形成的导流槽将防水卷材上层出水点分隔开，阻挡出水点横向蔓延，可将防水层上出现的水流导流至纵向盲沟中排出，实现导流功能，并增强防水卷材的强度。
虽然，上文中已经用一般性说明及具体实施例对本申请作了详尽的描述，但在本申请基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本申请精神的基础上所做的这些修改或改进，均属于本申请要求保护的范围。
